From ba7808eac17360dda459f82222859b0e3879854b Mon Sep 17 00:00:00 2001 From: Frederik Deweerdt Date: Sun, 4 Feb 2007 20:15:27 -0800 Subject: [TCP]: remove tcp header from tcp_v4_check (take #2) The tcphdr struct passed to tcp_v4_check is not used, the following patch removes it from the parameter list. This adds the netfilter modifications missing in the patch I sent for rc3-mm1. Signed-off-by: Frederik Deweerdt Signed-off-by: David S.
